FLEXIBLEBAG.

SPECIFICATION forming part of Letters Patent N 0. 735,560, dated August4, 1903.

Application filed December 5, 1902 Serial No. 134,004. (No model.)

To all whom it may concern:

Be it known that I, JOSEPHINE MI L TLLER, a citizen of the UnitedStates, and a resident of the city of New York, borough of Manhattan, inthe county and State of New York, have invented a new and usefulImprovement in Flexible Bags, of which the following is a full, clear,and exact description.

My invention relates to improvements in the construction of flexiblebags.

The purpose of the invention is to provide a construction of flexiblebag wherein a fabric is employed woven in a tubular shape and closed inweaving at one end, which tubular fabric is folded upon itself in suchmanner that the open end of the tubular fabric is carried inward indirection of the closed end and its open end is concealed, thusproducing a bag made in one continuous tubular length, which comprisesan outer wall or member and an inner wall or member independent of theouter one, the two walls being without a seam at the mouth and sides ofthe bag and the outer wall being without a seam at its bottom.

Another purpose of the invention is to provide draw-strings which extendthrough loops woven in the outer side faces of the bag,whichdraw-strings are interwoven or caged in said.

terminal above the free end of the adjoining draw-string.

The invention consists in the novel construction and combination of theseveral parts, as will be hereinafter fully set forth, and pointed outin the claims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the figures.

Figure 1 is a perspective sectional view of the improved bag. Fig. 2 isa vertical sec-' tion through the bag, and Fig. 3 is atransverse sectiontaken practically on the line 8 3 of Fig. '1.

The bag is constructed of a flexible material, a woven fabric beingpreferably used, and this fabric is produced in tubular form with oneend 10 closed in the process of formation, while the opposite end 11 isopen.

In the formation of the tubular woven fabric composing the body of thebag, at a predetermined distance from its closed end 10 at each 'side ofsaid tubular body, a transverse series of longitudinal loops 12 isformed, as is shown best in Fig. 2, and, further, in the production ofthe tubular body fabric the aforesaid loops 12 are made to cross andform guide-inclosures for two draw-strings A and B. Each draw-string isdoubled upon itself to form two members, which members enter theguide-loops from opposite edges of the tubular body fabric of the bag,and the two draw-strings are preferably placed one above the other, sothat in action one will not interfere with the other. I

A member of each draw-string A and B passes through the guide-loops 12at each side of the tubular body fabric, and the free ends 13 of onedraw-string are below or are associated with the loop 14 of the opposingdraw-string.

In the formation of the bag the tubular fabric body is folded, as shownin Figs. 1 and 2, so as to carry the open portion 11 of the body withinthe closed-end portion 10, the fold being made at a point above theguide-loops 12 of the body and the draw-strings A and B, thus producingouter walls 0 and inner walls D,- one independent of the other, from topto bottom of the bag. The open lower end of the inner member or wallD ofthe bag is closed by stitching or in any other approved manner, asisindicated in Figs. 1 and 2. Under this construction a flexible bag isformed of a continuous tubular body having independent inner and outerwalls, seamless edges 15 at the mouth, seamless side edges l6,and aseamless bottom edge for the outer wall; but the corresponding edge ofthe inner wall is closed, as'stated, in the completion of the bag, and,furthermore, the draw-strings are placed in position during theformation of the tubular body and are thus seated most economically andto the best advantage, being interwoven 0r caged, thereby addingmaterially to the strength of the article.

I desire it to be understood that while I prefer a woven fabric as thematerial from which to make the bag any flexible material in tubularform and corresponding seamless condition is included within the scopeof the invention.

Having thus described my invention, I

claim as new and desire to secure by Letters Patent 1. A flexible bagconsisting of a continuous tubular flexible material folded upon itselfto form two walls, an inner and an outer wall independent one of theother, the said bag being seamless at its mouth edge and at the bottomedge of its outer wall, as set forth.

2. As an improved article of manufacture, a flexible bag consisting of acontinuous tubular fabric having a continuous closure at one end andopen at the other, which fabric is folded upon itself to form outer andinner independent walls, the mouth-section and outer bottom section ofthe bag, together with the side edges of bothwalls, being withouta seam,

, as specified.

3. Asa new article of manufacture, a flexible bag consisting of acontinuous tubular fabric having a continuous closure at one end andopen at the other, which fabric is folded upon itself to form outer andinner in dependent walls, the mouth-section and outer bottom section ofthe bag, together-with the side edges of both walls being without seams,and the bottom section of the lining or inner wall of the bag beingconnected by a closing medium, as specified.

f. A flexible bag consisting of a continuous tubular fabric having acontinuous closure at one end, which fabric is folded upon itself toform outer and inner independent walls, the mouth-section and outerbottom section of the bag being without a seam, likewise the side edgesof both walls, means for closing the bottom portion of the inner wall, atransverse series of loops formed at the outer face of the outer wall,and draw-strings passed through said loops, as set forth.

5. A flexible bag consisting of a continuous tubular fabric having acontinuous closure at one end, which fabric is folded upon itself toform outer and inner independent walls, the mouth-section and outerbottom section of the bag being without a seam, likewise the side edgesof both walls, means for closing the bottom portion of the inner wall, atransverse series of loops formed at the outer face of the outer wall,and draw-strings passed through the said loops from opposite edges ofthe bag, a memberof each draw-string extending out at each side of thebag and the loop of one draw-string being adjacent to the free ends ofthe adjoining draw-string, substantially as described.

(3. A flexible bag consisting of a continuous tubular fabric woven inone continuous length and closed at one end in weaving, the open end ofwhich fabric is carried inward in direction of the closed end, forminginner and outer independent walls, and means for closing the inner openend of the inner wall, whereby initially the bag is formed seamless atthe mouth, its sides and the bottom of its outer wall, substantially asdescribed.

'7. A flexible bag consisting of a continuous tubular fabric woven inone continuous length and closed at one end in weaving, the open end ofwhich fabric is carried inward in directionv of the closed end, forminginner and outer independent walls, means for closing the inner open endof the inner wall, whereby initially the bag is formed seamless at themouth, its sides and the bottom of its outer wall,draw-strings bent uponthemselves and carried in opposite directions at opposite sides of thebag, the loop of one draw-string being over the free ends of theopposing drawstring, and transverse series of guide-loops at the outerfaces of the outer side walls of the said bag,which guide-loops crossthe drawstrings where they engage with the bag, the said loops beingpassed over the said drawstrings during the formation of the tubularbody of the bag, as set forth.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses. 4
